Classical machine learning and statistics datasets from
the UCI Machine Learning Repository and other sources.

The datasets package defines two different kinds of datasets:

small data sets which are directly (or indirectly with file-embed)
embedded in the package as pure values and do not require network or IO to download
the data set. This includes Iris, Anscombe and OldFaithful.

other data sets which need to be fetched over the network with
Numeric.Datasets.getDataset and are cached in a local temporary directory.
